I can't verify, but according to an article comment on serverfault[1], requesting the domain-name and host-name from the server negates the "send host-name" option. There were a few other suggestions in that article as well. Normally MS DHCP/DNS only allows secure updates, and this must be expressly changed to allow insecure updates. Either the insecure updates are enabled and that's how the Ubuntu machines work, or possibly the Ubuntu machines are doing something else (joined to the domain with likewise-open maybe? Using nsupdate to do a secure update, which according to a 2008 thread on a bind list is conceivable with BIND 9.5's nsupdate[2]).
